### cgram.y
The frontend. This file is really intuitive.
Reading through, you will find block, buildtree, branch, plabel, ecomp, tempnode and so on.
These functions are defined in trees.c.
### trees.c
You can learn much from buildtree(). Write a simple C program and "ccom -Xb" it.
Also see [[node_structure]].
